- You were required to send the resources through the EXO Request Platform with the
Medium Gas Canister, which can hold 160 items of one resource at a time. You could also send 8 individual resources on the side of the EXO Request Platform, resulting in a maximum capacity of 168 items per launch. Each launch of the rocket costs 500 Bytes, no matter if the rocket has a full load or not. - Players could only send the currently requested resource in the rocket, and would not be able to send any other resources of other tiers of the event.
